BIM專案成功的經驗法則

Abstract

BIM-Building Information Modeling technologies and workflows are embraced for delivering both building and non-building projects by the Global AECO-architectural, engineering, construction and operation Industry. It is expected that AECO organizations adopt BIM technology, define the process and develop internal policies to deliver projects at expected BIM maturity. Identifying the factors that are critical for successful delivery of BIM projects and defining BIM performance measures will benefit AEC organizations to reach their clients’ i.e. operation organizations’ expectations. As a response to the need, an empirical approach is proposed and applied to the study of BIM projects implementation process. With an initial step towards performance assessments in BIM projects, this study outlines the methodology to define the CSFs-critical success factors and corresponding OCSFs-operational critical success factors. An empirical approach is adopted in this study to define the list of CSFs and OCSFs for successful delivery of BIM projects in Taiwan’s AECO industry. The originality of this research is in a proposed approach that fits the necessities of successful delivery of BIM projects. The developed Framework of IFs-influencing factors can be altered to fit the needs of design, construction and operation organizations by retaining the necessary factor groups in the framework. The framework presented in this study is an outcome of a detailed study of the IFs identified from literature review, discussions with the domain experts and refinement of the framework in several sittings. A questionnaire was designed and targeted to Taiwan BIM experts to identify CSFs. The data collection process was accomplished in a FG-focus group meeting and few by email or post. The statistical methods such as respondents’ data summary, reliability analysis, t-test, and ranking analysis are employed in this study. Thirty-eight CSFs are listed from the ranking analysis. A breakfast meeting was held with these Taiwan BIM experts to validate the CSFs and brief them on the procedure to define OCSFs. A relationship mapping procedure was performed on a spreadsheet matrix with a selected set of Taiwan BIM experts to identify OCSFs through one-on-one meetings. The data collected from the set of experts has been compiled and analyzed. Thirteen OCSFs have been identified as a result of the relationship mapping and ranking analysis. FG meeting was set up to validate the OCSFs, and the validation process included OCSFs mapping with BSC-balance scorecard perspectives and BIM project objectives. The study results are beneficial to Taiwan’s AECO industry to comprehend the factors that are critical for successful delivery of BIM projects in the country. This study can also benefit the Global AECO industry with the proposed approach to define OCSFs for BIM projects. The results of this research set the foundation to define BIM performance measures that benefits the AECO organizations board members, management and project teams to predict the success of their BIM projects.
